IMPROVEMENT IN FRAMES FOR VERTICAL ENGINES.

Specification forming part of Letters Patent No. 141,467, dated August5, 1873; application filed March 22, 1873..

To all whom it may concern:

Be it known that I, GEORGE B. SIssoN, of the city of Buffalo, in thecounty of Erie and State of New York, have invented new and usefulImprovements in. Frames for Vertical Engines, of which the following isa specification:

This invention relates to the frames of vertical engines; and theinvention consists in forming or casting the said frame in two parts orhalves having a cored bed-plate, and each of the four standards having aknee at its base. It further consists in casting these standards withpermanent tubes, through which bolts are passed, in connection with aguide-yoke, and combining the latterwith reamfittings between the twostandards, thus bringing the two castings together and uniting theframe; the whole formed of three pieces of casting, as hereinafter fullyexplained.

In the drawings, Figure l is a perspective view of the whole frame. Fig.2 is a crosssection of a portion of the frame and yoke.

A A represent the four standards; B B

the bed-plates; and O O, the permanent tubes castonthestandards.Eachofthesebed-plates, with its two standards A and tubes 0, is cast inone piece, the bed-plate and each standard and tube being cored, makingthem very light,

but not at the expense of strength. The base of each standard has atrumpet-mouthed fillet. Cast with these are knees or webs D D, whichgive great additional strength to the frame, and do away with anynecessity for bolting or in any way staying the standards or frame,

' except through these knees, where thrust-bolts may be passed through,if desired. The cored bed-plates are finished up so as to fit closelytogether, and are tightly bolted underneath, thus making a sufficientbottom connection. The four posts slant inwardly, and each pair has caston them a side piece or connection, E, to add to their strength andassist in holding them in position. Just below these connections, andbetween the four posts, is arranged a yoke, F, cast in one piece, itsends a a coming in contact and between the ends of the permanent tubes 0O, and through which bolts 1) b are passed, and are secured outside eachpost by nuts, thus uniting the frame in a solid manner, and which allowsthe engine to be worked at a high rate of speed without jarring orloosening, and making an exceedingly simple construction. The inner endsof the tubes 0 O are cast with fillets to. add to their strength.

I claim- The vertical engine-frame cast in two pieces or halves, eachhalf comprising the standards A A, bed-plate B, permanent tubes 0 O, andhaving the yoke F connected therewith, the whole arranged andconstructed substantially as hereinbeforespecified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

GEORGE B. SISSON.
